It’s a great tactic at first light or right before dark. Bust them in the morning and you’ll have birds yelping, clucking, and kee-keeing from all directions within an hour or two. If you scatter them in the evening, just return to that spot the next morning and be patient. The urge to regroup is strong, especially early in the fall. Sit down and start with a few kee-kee runs, a high-pitched, pleading assembly call frequently used by single, lost birds. If one answers, just imitate what you hear, sit still, and keep your gun at the ready.
